Mob Posted December 27, 2014 Report Share Posted December 27, 2014 So I have been in search of the right shaft for my golf swing. Luckily, I have a very knowledgeable club fitter here in Indianapolis, who I just started working with on this project. In addition to the typical numbers that we all look at, he tends to look at the speed profile and acceleration profile, two of the tools on Flightscope, that help him see exactly how a shaft is performing. I may get this slightly wrong, but the speed profile gives you an idea of how the shaft works with the force you put on the shaft throughout the swing, and the acceleration profile can show you how the tip of the shaft is performing at the top of the backswing and at impact. If there is an upward deflection in the acceleration profile at impact, it means the shaft is too soft in the tip. If there is a downward deflection in the acceleration profile at impact, it means the shaft is too stiff. I went through a few shafts that I already know work for me, and we tested them all during a few different sessions. Diamana X 70stiff- Looked good overall. The speed profile indicated that I was having to work a little bit too much to get the shaft to do what I wanted, and I felt that to be accurate. UST Elements Chrome 6F4T- Looked good overall, but a little soft in the tip. Aldila Tour Green stiff- Everyone talks about how stout this shaft is, but the acceleration profile indicated that the tip was also a little soft for my swing. I struggled to hit it consistently, which goes along with a tip that is too soft. I really didn't love the feel of this shaft. Quadra Fire Express Max WBQ- Looked good overall. I honestly can't remember all the details of this one, but I think something about it was slightly wrong for me. Crazy CB LS Noir 7.4- Looked just PERFECT in both the acceleration and speed profiles. This was the shaft Tario fit me for via email 3 years ago. We started with the 7.7, but it felt too stiff for me, so we changed it to the 7.4 Obviously, each club had a different head, which would affect the numbers, but that is why I just wanted to share the speed and acceleration profiles, which are reflective of shaft performance, independent of club head, assuming head weights are similar. I guess I need to buy a few more of these, now that i know that it is the best shaft for my swing. He then put it on the MOI shaft analyzer and told me that my MOI to shoot for is around 2813, as that is what the Crazy measured. Quote Link to comment Share on other sites More sharing options...
kaaayelll Posted December 27, 2014 Report Share Posted December 27, 2014 I like the speed and acceleration profile idea. Thanks for the info. Quote Link to comment Share on other sites More sharing options...
Mob Posted December 28, 2014 Author Report Share Posted December 28, 2014 I like the speed and acceleration profile idea. Thanks for the info. It is pretty interesting when you have someone adept at it, explaining it. I barely understand it. It is neat to see the acceleration and speed profile lines in a shaft that is too stiff, not stiff enough, and just right. You can really see how the line changes with these different profiles. It was also interesting in how a shaft that felt "good", typically had a very smooth speed profile, compared with one that didn't match my swing. Most of the fitters I have used in the past ignore this function of Flightscope, because I don't think they really understand it themselves.

Ian-500 Posted December 30, 2014 Report Share Posted December 30, 2014 Great post. The shaft that had the best 'acceleration' and 'speed' profile, did it also have all the other 'numbers' that were the best for your swing, i.e. launch angle, carry distance, smash factor etc?

Mob Posted December 30, 2014 Author Report Share Posted December 30, 2014 (edited) Great post. The shaft that had the best 'acceleration' and 'speed' profile, did it also have all the other 'numbers' that were the best for your swing, i.e. launch angle, carry distance, smash factor etc? The best shaft for me was the Crazy LS Noir 7.4 and it is paired with a Crazy 435 head. I struggle with this head, as my miss is near the heel, which doesn't go well with this head. On well struck drives my numbers were: swing speed 101 mph (my typical ss is around 105 mph), smash 1.49-1.5, launch angle 12 degrees, spin 2200 rpm, ball speed was between 146-150 mph, carry yardage 240-250 yards, and total yardage 270-275 yards. I am going through a little bit of a swing change, so I am hitting the ball all over the face right now. I gave you the averages for my well struck drives only. Swing speed is down right now as well, but not sure why that is. I feel like I am swinging pretty hard, but the Flightscope disagrees with me on this point. I am going to buy another one of these shafts to keep, now that I know how well it suits my swing. I just went back to hit on the Flightscope again this morning and it confirmed the initial findings. Acceleration profile and speed profile still look much better with this shaft, than most of my others. The second best shaft for my swing was the Fubuki K series 60X.
